"She really can't be upset at a person she doesn't know," an insider told HollywoodLife about Gomez's feelings toward Jeffries.

"She hates that she is with him and thinks it should be her. But she knows Justin is steering the ship and instead of Selena being along for the ride, it's Chantel," the source added.

The former Disney star, 21, reunited with Bieber on Jan. 2 for a segway date and she was reportedly led to believe that there was a possibility for a reconciliation. Within a few weeks the "Confident" singer was spotted with Jeffries and Gomez was left devastated.

"The truth is, she's crushed ... And it's not just that Justin chose to go back to flirting with the nearest sexy girl; it's that he totally deceived her by feeding her lines about changing his ways, only to go back on those promises at the first turn," another source said.

Gomez and Bieber dated for three years before splitting up in May due to alleged trust issues, but the actress reportedly still loves him.

"Selena is sad but she's also angry. She feels like Justin played her because just when she was getting some closure and strength he convinced her to come back to him and made all kinds of promises," the insider explained.

"But it turns out they were all lies and now she's back at square one, trying to get over him all over again," the source said. "In a way she's mourning because she's realized that he just isn't the guy she fell in love with anymore."
